Nssha1

The nssha1 module provides the ns_sha1 function, which returns a 40-character, hex-encoded string containing the SHA1 hash of the first argument.

Example 1:

set sRawPassword "mypassword"
set sPassword [ns_sha1 $sRawPassword]
ns_adp_puts $sPassword
# 04003622EB9D0F788CE7568C7EED23809534365A

Usually this function is used with a salt, as without a salt it is succeptible to dictionary-based attacks.

Example 2:

set sSalt "salty"
set sRawPassword "mypassword"
set sPassword [ns_sha1 ${sRawPassword}${sSalt}]
# B48FB74597C11FC609DBE912992085EB07847FB6
